Aaron Tang (University of California, Davis – School of Law) has posted Second-Order Constitutional Theory (93 U. Chi. L. Rev. __ (forthcoming 2026)) on SSRN. Here is the abstract:
A sophisticated legal thinker who wishes to work out a fully developed approach to constitutional adjudication must choose two theories, not one. The first choice is familiar. What is the best approach for finding right answers to constitutional disputes? The leading competitors are familiar, too—theories such as originalism, pluralism, moral readings, and common law constitutionalism specify different kinds of arguments and evidence that are relevant to ascertaining “correct” constitutional interpretations.
It turns out, though, that a sophisticated legal thinker must also make a second theoretical commitment. For unless one takes the implausible view that every single case is an evidentiary wipeout under their preferred first-order theory, something more will sometimes be necessary to decide a case. That something is a second-order theory of constitutional adjudication: a theory that does not purport to make any interpretation more (or less) correct, constitutionally speaking, yet still guides a decisionmaker after their preferred first-order interpretive theory has run out.
This Article’s thesis is that the debate over second-order constitutional theories is both important and generative. It is important because reliance on second-order theories is inevitable in the hard cases that divide us—and because different second-order approaches will often lead to different outcomes. And it is generative because even though few judges or legal academics are likely to change their first-order commitments, our second-order preferences are nowhere near as sticky. Indeed, the dominant, yet unspoken, second-order theory embraced by today’s Supreme Court—the 51-49 rule, under which each justice votes for the outcome they think is supported by more first-order evidence than any other outcome, no matter how slight the difference—is far from inevitable. Yet it is the 51-49 rule, I will argue, that is as responsible for the acrimony over today’s Court as the first-order clash between originalism and its competitors. That claim, if proven, creates an intriguing possibility: armed with a better second-order theory, judges who disagree vehemently over how to interpret the Constitution might still find their way to consensus in some of the most weighty and difficult cases of the day.
Important and deep. Highly recommended. Download it while it’s hot!
